  • Constantly on the move and frequently make presentations at customer sites? This ultra-mobile projector offers a winning combination of ultra-slim lightweight design, exceptional image quality and advanced functionality.
  • With traditional wired and built-in wireless connectivity, time-saving set-up plus a range of advanced features, it's the ideal tool for polished presentations.

Exceptional image quality

  • Enjoy superb image quality, impressive natural colours with an equally high white and colour light output of 3,200 lumens thanks to Epson's 3LCD technology. True Colours technology delivers a faithful reproduction of colours as they are meant to be and, with a 10,000:1 contrast ratio, projected images are crisp and clear.

Easy set-up

  • Automatic vertical and horizontal keystone correction and Screen Fit makes it easy to set up the projector almost anywhere. The short throw ratio projects a large image from a shorter distance so that all meeting participants can be seated behind the projector as the front exhaust directs heat away from them.
  • Auto Power On turns the projector on when it detects signal input, and NFC makes it easy to connect to mobile devices using the built-in Wi-Fi connectivity.

Smarter presentations

  • Gesture Presenter allows users to advance through a presentation directly with their hands. Users can view two data sources side by side with split screen, and MHL can show high-quality video and audio content from mobile devices while charging them at the same time.

True portability

  • The ultra-slim form factor and lightweight design makes this the ideal projector for anyone on the move. A carry case is included and the projector fits easily into a standard laptop bag.
